iMac fails to boot - graphics issue?

I'm having an issue with a 2017 iMac - it doesn't boot - crashes about half way through Apple logo progress bar, often with some funny graphics displaying - e.g. half the screen is yellow.

I've reset NVRAM/PRAM/SMC, wiped hard disks and installed Big Sur, then upgrade to Monterey. Still I'm getting the same issue.

It does boot fine in safe mode...

I'm suspecting graphics card failure. I received these details on one failed start, can anybody help diagnose please?
