The grid size is part of the pattern in the same way that the colors are part of the pattern. It’s not just a color pattern, it’s a generalized mapping of input to output.
In short: you need to resize the grid because that’s what the examples do.
For two reasons:
1. The initially suggested grid size was 3x3.
2. Filling in a 3x3 grid is sufficient to show that you understood the pattern, but filling in a 1x1 (or even 2x2) grid is insufficient.
Requiring the user fill in a larger grid is a waste of time. The existence of the grid size selector would still make sense in cases where a 2x2 grid would be sufficient to show the solution, so it is not obvious at all that a 6x6 grid should be chosen.

To understand a pattern, you have to see at least two valid inputs and corresponding outputs. For the first example, a valid example for the expected output grid size is missing.
I arrived at the "correct" conclusion eventually, but the only indicator was that the reading direction for the UI was absolutely ridiculous ( https://i.imgur.com/CuQ2z2N.png ), suggesting that the authors did not think this through properly, so the solution had to be weird as well.
This is IQ tests all over again. Actually testing how alike you think to the author of the test.
This makes me think of "math" problems requiring you to find the next number in a series. They give you 5 numbers, and ask for the 6th. When I can build a polynomial than can generate the first 5 and any 6th number. Any.
Sounds like the point of these exercises it to guess what the author had in mind, more than some universal intelligence test. Though of course the author thinks their own thoughts are the measure of universal intelligence. It's a tempting thing to believe.
