Variable frame rate screens aren’t just for making the phone feel snappier but are also needed for the battery to last longer.

If your production volume isn’t high enough to justify a custom screen to be cut you are stuck with what is available on the market.

And even if 5” screens are available now in the form of NOS or upcycled refurbs that may not be the case 2 or 3 not to mention 5+ years down the line.

So you have to go with what not only is available today but with what is still likely to be available throughout the expected usable lifetime of your product.
