Actually, yes there are scriptures in Revelation that refer to the great tribulation saints being exposed to God's wrath, which I will describe below. But first, because God's wrath affects the entire earth, there is no way that no one can be affected by those plagues of wrath. In other words, just by being on the earth people will be exposed. Regarding this, consider the following:
Second seal: Peace is taken from the earth so that mankind kills each other
Third seal: World-wide famine, so that a small amount of food will cost a your entire days wages. And that's just food!
Fourth Seal: A fourth of the earths population killed as a result of the combined first four seals
First trumpet: A third of the earth and a third of the trees burned up. How many fatalities involved?
Second Trumpet: A third of the creatures in the sea killed and a third of the ships destroyed. How many people on those ships and how many people in those cities, towns and villages on every shore of that body of water will be killed?
Third Trumpet: A third of the rivers and fresh water is contaminated so that many people die from drinking it.
Fifth Trumpet: Demonic beings resembling locusts are released from the Abyss to torment the inhabitants of the earth.
Sixth Trumpet: Four fallen angels are released and with their demonic army of 200 million, kill a third of the earths inhabitants
Second Bowl: Ocean is turned into literal blood
Third Bowl: All fresh water, except for the Euphrates is turned to blood
Fourth Bowl: The sun is given power to scorch the inhabitants of the earth, searing them with intense heat. How many fatalities?
Now just looking at what I've listed above, you can see that no one on the earth is going to be able to escape the results of those plagues of wrath. Now getting back to your question, if we look at the information regarding those saints who come out of the great tribulation, we can see that they will in fact suffer from those plagues of wrath:
"For this reason, ‘They are before the throne of God and serve Him day and night in His temple; and the One seated on the throne will spread His tabernacle over them. Never again will they hunger, and never will they thirst; nor will the sun beat down upon them, nor any scorching heat."
1). Never again will they hunger
The reference to them never hungering or thirsting again, would demonstrate that they will have suffered because of the world-wide famine, as well as a third of the creatures in the sea dying as a result of the second trumpet.
2). Never again will they thirst.
The reference to never again thirsting, would be referring to when a third of the rivers and fresh water are contaminated, as well as when the ocean and fresh waters are turned to blood.
3). Never again will the sun beat down upon them nor any scorching heat
The reference to the sun not beating down on them nor any scorching heat, is referring to the results of the fourth bowl judgment when the angel pours out his bowl on the sun where it is given power to scorch people, searing them with intense heat.
So yes, these are some of the scriptures showing that the great tribulation saints will have been exposed to those plagues of wrath and that simply because they are on the earth.
