It kind of does via libva-gl which translates VDPAU to vaapi.

There is no quality difference in the video, there is only one way to decode H.264.
With streams or other sources that might contain errors you would probably get worse quality.
The only purpose of vaapi etc. is to reduce CPU and energy usage.
For low-resolution videos you can get better quality of subtitles by using e.g. -vo gl or vdpau.
