its best to wait and see, but their strategy seems to hold water.
think about it, emulated GPU´s are an approximation of the output, like "mathematically inexact" output pixels, even through perceptually they are as good and often better than the original.
even if you just draw a textured triangle, the texture sampling quality/output varies from different gpu families (even from the same vendor), so "drawing and testing against the framebuffer" is a somewhat strong check to see if the gpu is an tegra X1.
game code that renders using a shader and checks for the precise expected outputs in the framebuffer will fail in emulators (unless the thing is cycle accurate and has no enhancements!), so the games might need to be cracked.
and cracking/bypassing denuvo is a pain in the ass.
what this probably wont solve or seems to be tackling is switch piracy on real switch hardware.
