What trim or no trim?

[RrogerD]

Wondering what experienced tilers would do with a trim (or not) in these situations?
The first photo, the gap is about 20mm, tapering down to zero over about 1.5m in each direction. I've had to use hardi-backer to level out the uneven wall, hence the large gap. Is there a plastic trim suitable or, do I just use a sloping filler in-fill?
The second photo, the gap is about 10mm. Too thin to use tiles I thought. I'm thinking to just run a smooth bead of filler down it and then paint over in gloss etc.
What do we think?
Thanks.

A tiler would not tile to anything but a flat wall .

That's right. That's why I attached the hard-backer first.

So how have you got gaps on a flat wall?

Do you have anything useful to offer? Or just criticism?

That’s a question, not criticism.
