Safe Sleep
macOS also includes a deep sleep mode known as Safe Sleep. Your Mac might enter Safe Sleep if your battery begins to run low, or your computer is left idle for a long time.
Safe Sleep copies the contents of memory to your startup drive and powers down the computer, allowing you to pick up where you left off without losing your work.
To wake your Mac from Safe Sleep, press its power button. If you use a Mac notebook and its battery is low, connect the AC adapter first.
When you wake your computer from safe sleep, a progress indicator appears. This indicates that the previously stored contents of memory are being read from the startup disk and copied back into RAM.

I’m getting this now with my new tb 2017 macbook pro. I was originally getting the static screen. After doing a nvram reset, I get this screen but with a singular loading bar as opposed to the small spaced out ones. Do you guys know if this goes away over time?
I'm sorry but I can't really visualize what this issue is. Is the loading bar you're speaking of the regular startup loading bar, but the issue is that it now happens when you wake the MacBook from sleep? Maybe an image would help?
You described it perfectly. It’s the wake up loading bar after waking up from sleep.
How's the wake-from-sleep behaviour? Does your Mac act as if it has just restarted (applications take time to startup) or does it act as if applications have been kept in RAM and are just immediately available (default sleep behaviour)? I guess the issue is that the Mac is taking a long time to recover from sleep?
Default sleep behaviour. That screen pops up for 1-2 seconds max. Everything works smoothly after.
Apologies for not being more helpful but my best guess is that it's standby mode. https://support.apple.com/en-sg/HT202824. It's basically hibernate/safe sleep for SSD Macs.
However, I have not seen what you've described on my own SSD MacBook; I've only experienced seeing the regular startup loading bar with my desktop background (not the black background with Apple logo).
Standby Mode
For Mac computers that start up from an internal SSD, macOS includes a deep sleep mode known as Standby Mode.
Mac computers manufactured in 2013 or later enter standby after being in sleep mode for three hours. Earlier models enter standby after just over an hour of sleep. During standby, the state of your session is saved to flash storage (SSD). Then, the power turns off to some hardware systems such as RAM and USB buses.
Standby extends how long a notebook computer can stay asleep on battery power. A notebook with a fully charged battery can remain in standby for up to thirty days without being plugged in to power.
