Details like hull plating seams and/or aztecing and the metallic look of the DSC Enterprise would have been enough to make the old girl look more updated.
In the end, the angled pylons, big impulse deck and the saucer lights/windows are the only major differences and those could have been left off. From certain angles, it looks like the same ship with HD level detailing.

I think I would've accepted the ship being squished vertically, or the angled pylons, but both was a bridge too far for me. I can see why they were done, shorter makes the ship look sleeker, and rear-swept pylons give the profile an appealing symmetry, but they also both take away the essential TOS-y-ness of the TOS-Enterprise. The swept pylons, while the bigger win aesthetically, are probably the ones that most need to go, because the straight pylon is the biggest distinction in the silhouette between the TOS ship and the refit.
