I just noticed this when watching youtube. I'm just about to turn the caption on by selecting the CC icon on [MORE OPTIONS] and noticed a new button called [Quality].
Upon pressing, you'll presented with video quality options from 144p to the highest according to the uploadee video for intance 4k.
P.S. I don't know how to add photo in a post so here's the link for the photo i've taken.

Had to uninstall updates and then re-update it.
