I personally would get five more years out of this kitchen.

I don’t think it’s dated. Yes, the trend is toward white and quartz.

If you feel an update here will greatly impact every where else maybe you need to wait a bit longer for when you are ready for a complete overhaul.

Putting white cabinets in that kitchen would be a mistake since the rest of your home does not lean towards it. I'd update the backsplash, lighting and switch out the glass door by the range hood for a solid door. I'd put the glass door on another cabinet.

New pendants and barstools would be fun to see where you could take the style quotient since that is your main issue.

Agree with the others- this kitchen could go far with some styling. Changing the fixed elements and/or painting the cabinets is Expensive, and the cabinets/granite/tile you already have are almost new and just fine- you won't notice them if you style the space well. Replace the stools with something that looks more comfortable. Get some really nice lanterns/lights or a linear chandelier. Invest perhaps in a Roman shade over the window, using a pattern or trim with colors to pull in other aspects of your decorating in adjacent spaces. Be sure to tie in the color of the cabinets to that fabric. Flowers and a bowl of fruit on the island, some attractive cutting boards leaning up against the backsplash, a tray with salt/pepper/oils, a crock with attractive utensils next to the stove- you can pull this together! It will still cost a bit, but thousands less than painting the cabinets (minimum $3K to 5K for a good job, plus the horrendous inconvenience of spray-painting in your house and waiting weeks for it to cure).
