Is this much slope acceptable for an LVP installation (pics)?

This is a tiny (6x6) bathroom in a rental, that had cracked tile and rotted joists from decades of leaks/tenants. I hired someone to remove the floor, repair the joists, and install subfloor/LVP. They did a great job with the joists and waterproofing the subfloor, but when they added self leveler, one half of the room was quite a bit higher than the other. I thought they would grind it down to even (or build up), but they didn't. I walked on it after the LVP was in place, and it was immediately apparent. We talked it over, and they were very willing to take the flooring out and build up the low side.

They did, and it is way better than it was before, but it is still unlevel. At the door, for 2 feet, it is almost perfectly level, then it dips down. If I put the level on the flat part, it takes 8 quarters on the low side to make the bubble level. Basically a 1/2" and a bit more as you go the last few inches to the tub.

I'm I overreacting or should it be more level than that? It's a bathroom, so I'm not sure if there are issues with using 1/2" more of leveler, but what I looked up says that this leveler (Henry Levelpro 555) can go 3-5". This is an old house, and it could be a structural issue causing the slope in the middle of the room, but isn't the self level product supposed to solve that?

These are really nice guys and I hate to go back a 2nd time about it, but if it can be improved, now is the time to do it. My problem is that I have no reference point about what is and isn't acceptable. Structurally I'm sure there is zero issue as is, but the slope is noticeable, although not massively.

Tenants may never notice it, but if $10-20 more of leveler could get the floor level, it seems like that should be the way to go.

What do you think? Am I overreacting? Is this an acceptable result, and nothing to be concerned over?

The room:

This is the amount of slope at the tub. At the door, the bubble is almost perfectly level:

The level in the middle of room, with 8 quarters on the low side:

Floors don't need to be level, they need to be flat. So you need a longer straight edge and look for any humps or dips that are more than 1/8" in 6 ft.

I prefer flat and level. A flat floor that is not level could prevent a plumb door from opening fully without cutting the bottom of the door.

Level is not really that important, as long as the floor is flat.

Since the floor is so out of level... Did you check the tub to see that it still drains. Hopefully the floor is sloping towards the drain end.

Did anyone bother to investigate why the floor is so out of level? Have the water leaks been repaired?
