Tempature makes a huge difference, now with your 500M readings on a LV motor you should be good no matter what but the readings are useless for trending in the future without the tempature. What happens in a year or 2 when you test this motor and the tempature is different? The most valuable info you get from an IR test is not so much what it is today but what the trend is over time for predicting failure.
A spot test only measures one if the 3 insulating properties of insulation so you are only getting part of the story. DAR is key info for a LV motor.
