Yes, Aruco are able to detect gray image. 

frame = cv2.imread("aruco_captured_image.png")
gray = cv2.cvtColor(frame, cv2.COLOR_RGB2GRAY)
aruco_dict = aruco.Dictionary_get(aruco.DICT_6X6_250)
parameters = aruco.DetectorParameters_create()
corners, ids, rejectedImgPoints = aruco.detectMarkers(gray, aruco_dict, parameters=parameters)

This worked fine for aruco detection as a I passed the single captured frame.
