Do I need a colorimeter with these monitors?

Factory calibration is accurate enough for hobby photography. Professional photographers should invest in a colorimeter (X-Rite i1Display or Calibrite ColorChecker) for hardware calibration every 4-6 weeks. Even the best factory calibration drifts over time.

Is 4K enough resolution for photo editing?

Yes. 4K at 27 inches (163 PPI) provides more than enough detail for evaluating photos at 100% zoom. 5K is slightly sharper but the difference is marginal for photo editing. Resolution matters less than color accuracy for this use case.
