Boeing have designed the secondary engine instruments to automatically display when certain thresholds are reached, this brings it to the attention of the crew. If the secondary engine indications are permanently displayed in the compact format this pop up feature is inhibited and therefore detracting from allowing the automation to alert the crew.
Boeing have multiple individuals that are experts in the field of Human Factors (Phd's) working on these areas, not to mention certification requirements.
Don't over think things.
