What if these filters also cure cancer by some mechanism that isn't known yet? Who knows, it might be true! After long experimentation with warmer lighting my cancer is gone, so it definitely worked for me.

What you're saying is not science either. The entire medical usage of blue light filters hinges on just a few papers. If you really can prove those studies inapplicable you can prove that there's no objective reason to use them (I'm not necessarily saying the author did that).

Whether these filters feel nice is entirely unrelated question, nobody stops you from decorating your living space as you see fit.
