I made one return on the PS5 in a similar situation, and it was a painful ordeal.

I don't give a shit for the money, but fucking my social gaming time was unforgiveable. I still use Steam, but don't fucking trust Valves return policy.
If a Valve employee with rights to look into it is reading this - I'd love to know what I did so wrong. But given that human explanations from modern software based corporations are non-existent, I will assume I was treated as per their returns policy.
And the outcome has worked in Steams favour. I buy for (account) life now, for better or for worse. As previously mentioned, I don't care about the money so much as the social.
But my decision making process to drop the significant money required for Steam hardware will assume the return/warranty is worth precisely zero.
