Does Dulux Trade solvent satinwood go yellow? And is trade PBW different to the normal one?

I painted some of my doors and skirting Timeless satinwood last year, as I didn't want the too clinical look that PBW seems to be known for. However, I don't like it. I can't quite put my finger the reason. It is a white, just looks a bit dull.

I have read some posts that suggest Dulux Trade is a good white and isn't as stark as PBW, but I'm not sure if they mean the Trade version of PBW or another shade?
I also can't seem to find a definite answer on whether it will go yellow, most answers go on to talk about yellowing gloss rather than satin.

I am just after a 'plain' but proper white, hope that makes sense!

Not helpful but I used Ronseal ‘lifetime guarantee no yellowing’ gloss in pure brilliant white and OMG that shit is white.

I’m about to change to Timeless satinwood. Your description of it is exactly the break my eyes need. 😂

Thanks, I always thought Rustoleum just did wood stain for some reason.

It may well just be my house/eyes but there's just something about the timeless. It makes my woodwork look odd. Thinking about it I may well have used eggshell (I had about 7 tins on the go trying to find a colour) so satin might be better!
