Vinyl LVT OK On This Floor?

Got a floor that is mostly level and flat for my kitchen that I want to put LVT tile on (floating floor kind). Most of the kitchen is old marley type tile and perfectly level (see picture 1). However there is then a transition (see picture 2) which is a very slight slope, then the floor is perfectly level again.

Now this little transition is very very slight, but has the odd little bump or two - which I hope is nothing, I have shown on pictures, 3 & 4.

I understand LVT as vinyl is a bit more flexible then say laminate, and I think whats best is to lay a LVT underlay which I understand are like 1-2mm, which should cover these little 'harsh spots' and then be good to go?

Does this all sound right? Want to try and avoid screeding if possible - but if I must, then I will.

I’ve just bought some Moduleo Layred vinyl laminate with its own built in underlay which I’ve still to lay but I am going to lay it on 9mm ply to smooth it out. You may get a bit of bounce on that transition and while I know very little, if it was me I'd level that off somehow, possibly by using some self levelling compound. Here’s an installation video of the flooring I have and you will see it gives a 5mm tolerance over a 2m length.

Floating vinyl is very susceptible to joint failure on uneven surfaces, best thing would be to self levelling screed to limit the transition area and if fitting click LVT choose a very very firm underlay.

Laminate would be more forgiving.
