Settle an Iitala Ultima Thule disagreement please.

I have a nice bowl that I believe to be Ultima Thule. My friend who has a shop that I consign in sent it back because the raised "bubbles" on the bottom are more widely spaced than in Ultima Thule examples in her shop. I found a piece, different size and form, of contemporary IItala Ultima Thule with the wider spacing of "bubbles" or bumps found on my piece. I believe it to be a discounted piece of recent Iitalla Ultima Thule, although I have not been able to find it on the internet. I want to put it out in my shop and do not want to misrepresent it. My friend thinks that it is a knock off!
It is just over 10 3/4 inches and diameter and 3 1/8' tall. Photo of the pesky bottom to follow.

We need a side-on shot, but i think this a the big bowl from a fruit set, along with
several smaller bowls.

It doesn't look right to me, tbh. The surface texture looks wrong, and the bubbles should be in the centre

Ultima always goes "back in on it's self" if you know what I mean.

Hello Denbydump, NaomiM. There is a contemporary piece with a wider bubble spacing, a serving platter. However, I agree with Denbydump- the rim is all wrong. I now think it is knock off and shall identify is as such. Sign and boo hoo.

The textured pattern on the side looks wrong for Thule too...
