You mention the patchy grout and it being gunmetal, so I assume it’s Bal?
I have used Bal grout for many years and Gunmetal has been very popular but I could grout 10 bathrooms and it will be fine and then 1 will be patchy and I have mixed it and washed it exactly the same. 🤷♂️
I find going over it with fine wet and dry sandpaper can sort it out.
