Lighthouse report for AMP pages shows low score and higher load times.

We have a fully valid AMP page, however, while running a lighthouse report, the score ranks in 60's. I tried testing with AMP CDN cache, same issue.

Is there any way to get actual score when the page goes live? https://github.com/GoogleChrome/lighthouse/issues/4490#issuecomment-364437127 says that this is an inherent limitation on how score is calculated for AMP pages, wanted to see if there's any update given all the changes in LHR.
#### Provide the steps to reproduce
1. Run LH on https://mutesix-pfpmarketing-com.cdn.ampproject.org/c/s/mutesix.pfpmarketing.com/amp/spend-10k-day-podcast-podcast-episode-2-find-right-attribution-model-business.html
OR
https://mutesix.pfpmarketing.com/amp/spend-10k-day-podcast-podcast-episode-2-find-right-attribution-model-business.html

#### What is the current behavior?
Score ~60

#### What is the expected behavior?
Score > 90
