Yes... From the front left corner to the back right corner you have 2 mm of difference in height. The good news is it appears the bed is pretty flat. You should manually level the bed as best you can. Lower the front left corner .5 mm and raise the back right 1 mm. Then re-run the test and level it a little bit more. Even though it seems like you should be able to do the entire correction at once, it never works out that way. Just keep raising the low corners and lowering the high corners a couple of time.

When you get it much more level than it is now, you will be able to see if you have high or low spots on your bed. As you scan left to right or up to down, if you see the sign flip from + to - and then go back to + (or vice versa), that will indicate a low (or high) spot on the bed.
