To the extent that's true, it's primarily the result of more advanced technology having become more commonplace in real life, and thus available to be utilized by film and television productions. TOS looked as it did because it was created with 1960s technology, with an eye toward 1960s aesthetics, and with the intent of being shown on 1960s television screens. The same goes for TNG in the 1980s, DS9 and VGR in the 1990s, ENT in the early 2000s, and DSC today. What we see in any given artistic portrayal of the fictional Trek world tends to represent rather more the limits of what its makers were able to conceive of and realize within their allotted time and budget, using the resources they had at hand, and to the dramaturgic effect desired in context of a given plot, than it does those of what is possible to imagine in-universe.
As I know I've pointed out before in these discussions, The Making Of Star Trek documents that Roddenberry envisioned Kirk's Enterprise as being equipped with holographic accoutrements and dispensing reconstituted clothing all along:
MEN AND WOMEN ON A STARSHIP, SO LONG OUT OF CONTACT WITH EARTH AND SO LONG AWAY FROM OTHER PLANETS, TOO, WILL REQUIRE A FEELING OF FRESH AIR AND SKY AND WIND AND SCENTS. BECAUSE WE ARE, IN MANY RESPECTS, STILL ANIMALS, OUR MENTAL AND EMOTIONAL EQUILIBRIUM WILL REQUIRE THE FAMILIARITY OF THIS. MAN HAS BEEN TOO LONG A PART OF EARTH TO BE TOO LONG SEPARATED. THEREFORE WE INTEND TO BUILD A SIMULATED 'OUTDOOR' RECREATION AREA WHICH GIVES A REALISTIC FEELING OF SKY, BREEZES, PLANTS, FOUNTAINS, AND SO FORTH. ONE OF THE REASONS FOR MAKING A STARSHIP SO LARGE WOULD BE TO HAVE SOMETHING LIKE THIS...
The fourth major facility on the eighth deck level is the entertainment center. Certainly man of the future will require entertainment as much as we enjoy motion pictures and television today. Probably entertainment will be three-dimensional in nature and perhaps will go even further, in that you will sit in the room and the story will take place all around you. In other words, a sophisticated extension of holography.
This technique will also have its effect on the traditional "mail call." Instead of receiving a letter, a man can sit in the room and, via tape, actually "see" the person sending the correspondence. As the tape is projected, the images will form in the air in front of him, so he will be able to see how his child looks, what's happening to the house, and how great his grandmother looked that day. It will be just as if he were standing there with them. Having used the "projecting unit," he can then use the "photographing unit," do a similar thing himself, and send it home...
Ship's laundry bears little resemblance to its 20th century ancestor. Primarily because garments are reconvertible. It is simply easier to put a garment into the processing machine, reduce it to its original chemical fibers, take out the dirt, and then recreate a "new" garment back into its original form...
And per the Deep Space Nine Companion, when Ronald D. Moore added holo-communicators to DS9, his reasoning was as follows:
That's something I had been pushing for because I just think it's so absurd that in the twenty-fourth century they have holodeck technology that allows them to recreate Ancient Rome, but everybody talks to each other on television monitors. It's just so lame. The viewscreens have been around for over thirty years. Can't we move to something a little more interesting? But it's like pulling teeth...
