It looks like I'm too late to change the outcome here but I did want to say that the right solution would be silicone in the change of plane. There are color matches for just about every grout color out there, either from the manufacturer or third party suppliers. Most of them now aren't shiny so they look much more like the grout than they used to.

Hard grouting shower corners seems to be one of those hot button topics where many installers line up against doing it and many line up in favor of doing it. However, the industry says to use silicone so if you're not doing that, you're carrying the liability if something goes wrong. And it will. The industry didn't take that position because it was popular or to make you buy expensive caulk, they did it because corner cracking in showers is a very common result of using grout in the corners.
