Bath edge not straight

[pixxyco]

Hi, fitting a Milan L Shaped bath and have spotted the top surface the hinged shower screen sits on isn't very flat, it has a curve in it with 6mm gap at wall and and about 3mm at L point. I've attached pictures.
I personally think this is too much of a curve to fit, what's others opinions?
Thanks

**** quality but the screen will be fitted to the wall at the low point, so may not affect the overall seal.

Question is, can you return it? If not then not a lot of other options.

It was from Victoria plumbing who are crap to contact, waiting for their technical department to reply but not holding my breath.
Just fitted a trajan bath that was curved on shower screen side, didn't spot until in, in my own house and son soaked floor on first shower So not keen to fit this bath and have hassle after
