As much as I adore some youtubers who point out Star Trek Discovery (aka DIS, DSC, DISCO, STD, Septic Tank Dirty, etc)'s flaws, they're wrong on this issue.
Look at "The Cage". Unlike "Where No Man Has Gone Before" where Spock is hollering, in the former he's traipsing around the alien environment and grinning over big green plants making sounds similar to the transporter. And hollering later on, jumping over things, screaming "THE WOMEN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!", etc. Enough of a case can be made that Spock did grow over time, which TOS affirms in "Plato's Stepchildren", "Journey to Babel", and others. Enough of a case can be made that Spock wasn't shown much in "The Cage" so there is a lot of creative leeway available.
My guess is they'll probably manage to screw it up royally and win an award for "best dramatic presentation".
