It's a bit of an other way around.
a 4k screen reduce your need for anti alias.
However TAA is not only anti alias anymore, its a bad technology being stretched as much as an anime girl in the hands of dobson.
All TAAs including DLSS work by deforming the last frame to look like the current frame, and combining em.
In the actual original purpose of anti-alias it was used by shifting the picture around in sub pixels, so with enough accumulated frames, you had something that looks like FSAA if done right, and assuming the "deform the last frame" step was done perfectly (it's not, DLSS is better at it but still not perfect).
Now they accumulate shadows (drawing noisy shit that accumulates into soft shadows), accumulate ambient light, accumulate raytracing, accumulate shifts in full pixels to stretch the resolution and all that.
However the whole "deform the last frame" step is still imperfect, so you see everything fall appart in motion.
That fast fusion for the switch 2 is the perfect example, as it tries to accumulate 1080p from 360p, but the game as the name implies is fast, and the whole "deform frame" fails catastrophically on it.
