Faulty formulation: If the inhabitants of Paradise see Allah, they must also grasp His full reality, manner and limits.
Correct formulation: The vision of Allah in the Hereafter is affirmed for the people of Paradise, but it does not make Him comparable to creatures or imply full comprehension of His essence or modality.
وَالرُّؤْيَةُ حَقٌّ لِأَهْلِ الْجَنَّةِ بِغَيْرِ إِحَاطَةٍ وَلَا كَيْفِيَّةٍ
The vision is true for the people of Paradise, without encompassing or specifying its manner.
Affirming vision and denying complete comprehension are therefore consistent.
