The channels are CAN_H (red), CAN_L (blue), and CAN_H-CAN_L (brown).
It can be observed in the diagram below that CAN_H-CAN_L has an acceptable signal shape. However, both CAN_H and CAN_L look poorly to me. And actually the device is not running in a noisy environment. I have two questions:
Do you think signal integrity is an issue here?
CAN_H-CAN_L sometimes has high voltage level of 1.65 V (left side part), while sometimes it has a high level of 2.06 V (right side part). Do you think this is a problem?
