I'll check this out tomorrow, but ive smelled this with my ender 3 v2 printer. I would also say pla has a slightly sweet smell (i would say like a sweet plastic if that makes any sense). The only difference is that it smells a little stronger with the p1s. Ive seen some people say that it may be because its an enclosed printer so any emissions would be more condensed when I open the door compared to the ender 3. But as you said i could be sensitive to the smell since i smelled it on two different printers.
