Sony A7r III focus point not visible?

[haring]

Hey guys!

I find the focus point of my a7r III not really visible compared to the focus point of my Canon 5d.... A lot of times I am struggling to find where the focus dot is. Is there a way to make it more visible? Anybody else experienced this?
Is there a way to improve the responsiveness and visibility of the AF (square) dots?

Thanks!
